The getSequenceNumeral function generates a sequence numeral by calculating the sum of multiples of a given prefix pre at each power of 10, and adds the remainder of a count count divided by 10.

The function takes two parameters: pre and count, and returns the generated sequence numeral, as demonstrated in the example getSequenceNumeral(3, 1).

Cell 2

function getSequenceNumeral(pre, count) {
  var digitCount = Math.ceil(count / 10) + 1
  var result = 0
  for(var i = 1; i < digitCount; i++) {
    result += pre * Math.pow(10, i)
  }
  return result + (count % 10)
}

getSequenceNumeral(3, 1)

/**
 * Calculates the sequence numeral for a given prefix and count.
 * 
 * The sequence numeral is calculated by summing the prefix multiplied by

 * of the count modulo 10.
 * 
 * @param {number} pre The prefix to use in the sequence numeral.
 * @param {number} count The number of items in the sequence.
 * @returns {number} The sequence numeral.

function getSequenceNumeral(pre, count) {
  // Calculate the number of digits in the sequence
  const digitCount = Math.ceil(count / 10) + 1;
  
  // Initialize the result
  let result = 0;
  
  // Use a loop to sum the prefix multiplied by powers of 10
  for (let i = 1; i <= digitCount; i++) {
    // Use Math.pow for exponentiation, but consider a more efficient approach
    result += pre * (10 ** i);
  }
  
  // Add the remainder of the count modulo 10 to the result
  result += count % 10;
  
  return result;

// Example usage:
getSequenceNumeral(3, 1);

Function: getSequenceNumeral

Parameters

• pre: The prefix digit to be used in sequence generation.
• count: The number of which the sequence numeral is to be generated.

Returns

The sequence numeral generated based on the provided pre and count values.

Description

This function generates a sequence numeral by calculating the sum of multiples of pre at each power of 10, up to the number of digits required to represent count. The final digit of the sequence numeral is the remainder of count divided by 10.

Function Implementation

function getSequenceNumeral(pre, count) {
  // Calculate the number of digits required to represent count
  var digitCount = Math.ceil(count / 10) + 1;

  // Initialize the result variable
  var result = 0;

  // Calculate the sum of multiples of pre at each power of 10
  for (var i = 1; i < digitCount; i++) {
    result += pre * Math.pow(10, i);
  }

  // Add the remainder of count divided by 10 to the result
  return result + (count % 10);
}
